Starting the Engine
WARNING Be familiar with the “Mandatory Safety Shutdown Procedure” on page 9 before starting the machine. Always perform this procedure before exiting the machine. Note: The machine cannot be push- or tow-started. Attempting to push/tow start the machine may damage the drive systems of both the machine and the push/tow vehicle.
WARNING Do not use starting fluid (ether). An explosion can result, which can cause engine damage, injury or death. 1. If the machine is equipped with the battery disconnect switch, check that switch is the “ON” position. See “Battery Disconnect Switch” on page 52. 2. Carefully step up onto the back of the bucket or attachment and grasp the hand-holds. enter the operator’s compartment and sit in the operator’s seat. Adjust the seat as required. See “Operator’s Seat” on page 29.
CAUTION All controls must be within easy reach. The operator must be able to move all controls through the complete range of motion. 3. Close the door, if so equipped. Perform the seat switch safety interlock test on page 30. 4. Fasten the seat belt(s). See “Fastening/Unfastening the Seat Belt” on page 30.
WARNING Always fasten the seat belt before operating the machine. Repair or replace any damaged seat belt and lock parts before operation. 5. Lower the operator restraint bar. Important: The operator restraint bar must be lowered before the engine can be started. 6. Place the lift/tilt, drive and auxiliary hydraulic controls into the neutral position. 7. Make sure no persons are hazardously close to the machine.

8. Turn the ignition key one detent clockwise to the ON/RUN position. If the engine is cold, the pre-heat ( ) indicator activates. For information Figure 53 – Ignition Keyswitch about starting in colder ambient temperatures, see “Cold-Starting” on page 58. 9. When the pre-heat ( ) indicator goes out, turn the ignition key all the way clockwise to the START position to engage the starter. Important: The recommended limit of continuous starter engagement is 15 seconds, and the starter must never be energized for more than 30 seconds. If the starter is energized for 20-30 seconds, the ignition should be turned off for one minute or longer. To protect the starter (DPF Models), the E-ECU system turns off the starter circuit if it is energized for 30 seconds or longer. The starter will remain de-energized for 30 seconds more before the engine can be restarted. Important: If the engine fails to start within 15 seconds, turn the key all the way counter-clockwise to the OFF position and check for engine error codes on the information center display (page 108). Allow the starter to cool for 20 seconds and repeat steps 8 and 9.
Cold-Starting If operating in temperatures below 32°F (0°C), the following are recommended: • Replace the engine oil with the proper viscosity oil according to the engine operator’s manual. • Make sure the battery is fully charged. • Install an optional block heater on the engine. A block heater is recommended for starting in temperatures below 20°F (-7°C). Contact your dealer for engine heater options. Run the engine at 1800 rpm with no load for 5 minutes to warm the engine and hydraulic fluid to operating temperature before operating the machine. Note: Depending upon coolant temperature, 50° F (10° C) or below, the low idle engine speed is automatically increased during a five minute warm-up period or until the coolant reaches a specified temperature. Important: In ambient temperatures below -10° C (14° F), an engine block heater is recommended and is required below temperatures below -15° C (5° F) to reduce starter load and aid engine warm up.
